In general, speaking before a group or talking on the telephone may make a personâs stuttering more severe, while singing, reading, or speaking in unison may temporarily reduce stuttering. Stuttering is sometimes referred to as stammering and by a broader term, disfluent speech. Who stutters? Roughly 3 million Americans stutter. Stuttering affects people of all ages. It occurs most often in children between the ages of 2 and 6 as they are developing their language skills. Approximately 5 to 10 percent of all children will stutter for some period in their life, lasting from a few weeks to several years.
A coordinate bond (also called a dative covalent bond) is a covalent bond (a shared pair of electrons) in which both electrons come from the same atom. A covalent bond is formed by two atoms sharing a pair of electrons. The atoms are held together because the electron pair is attracted by both of the nuclei.
Unlike ionic bonding, covalent bonding may have single, double bonds or triple bonds between two atoms. These bonds are formed in such a way that the two atoms obey the octet rule. The bond occurs via the overlapping of atomic orbitals. A single bond is formed when two electrons are shared. A double bond is formed when four electrons are shared. Sharing of six electrons may result in a triple bond. The characteristics of compounds with covalent bonds include strong bonding between two atoms due to similar electronegativity values.
